Dust Proof Anti Moisture Corrosion Resistant Labyrinth Seals for Conveyor Roller Bearing Housings

Labyrinth Seals for Conveyor Roller Bearing Housings

Advantages about Roller Plastic Seals:

Labyrinth seals are an essential component in modern conveyor roller systems, ensuring smooth operation

and long-term performance under tough operating conditions.

Contamination prevention: Blocks external contaminants such as dust, dirt, sand, and moisture

from entering the bearing. 

Lubricant retention: Prevents the lubricating grease (or oil) inside the

bearing from leaking out. 

Wear reduction: Isolates hard particles (e.g., abrasive particles) to prevent abrasive wear on the bearing

raceways and rolling elements.

Lightweight and corrosion-resistant: The plastic material is lightweight and more resistant to moisture and

chemical corrosion compared to metal seals.

Production process of plastic seals for bearing housings:

1, Prepare mold and test it;

2, Slice the raw material to circular blank/disc;

3, Extend circular disc step by step after blanking;

4, The workpiece get further reshaped;

5,Scrap edge and punch the workpiece to form a upper hole, then a bearing housing is well finished;
